Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0031] A protective cover for an LED display screen, including a box body 1 and a box cover 2, further including:

[0033] The first buffer pad 4, the first buffer pad 4 is arranged above the inside of the box body 1, and is used for fixing the upper part of the LED display screen and buffering protection during transportation;

[0034] The second buffer pad 5, the second buffer pad 5 is arranged on the inner bottom surface of the box body 1, and there are multiple second buffer pads 5, and is used for supporting the lower part of the LED display screen and buffering protection during transportation;

[0035] The buffer fixing mechanism 6, the buffer fixing mechanism 6 is arranged on the inner side surface of the box body 1, and there are multiple buffer fixing mechanisms 6, and is used for fixing the side surface of the LED display screen and buffering protection during transportation. When the LED display screen is placed or taken out, an operation space for placing or taking out the LED display screen can be left to avoid friction between the LED display screen and related structures during placement or removal, resulting in inconvenient placement or removal operations of the LED display screen;

[0036] Adjusting mechanism 7 is rotatably connected to the inner surface of the box cover 2 and is used for adjusting the height of the first buffer pad 4 to meet the requirements of effectively fixing and buffering and protecting LED display screens of different sizes. The first buffer pad 4 is fixedly connected to the adjusting mechanism 7.

[0037] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the buffer fixing mechanism 6 includes a first telescopic cover 61 arranged on the inner side surface of the box body 1. A connecting plate 62 is arranged on the outer surface of the first telescopic cover 61. A third buffer pad 63 is arranged on the outer surface of the connecting plate 62. A plurality of limiting rods 64 are arranged on the outer surface of the connecting plate 62 close to the first telescopic cover 61. The plurality of limiting rods 64 are all slidably connected to the box body 1. A tension spring 65 is sleeved on the outer side of the limiting rod 64. The plurality of tension springs 65 are all fixedly connected to the connecting plate 62. The plurality of tension springs 65 are all fixedly connected to the box body 1. A transmission mechanism 8 is arranged inside the first telescopic cover 61. The box cover 2 is rotatably connected to the transmission mechanism 8. The plurality of connecting plates 62 are all in contact with the transmission mechanism 8. The transmission mechanism 8 is fixedly connected to the box body 1.

[0038] Specifically, as Figure 2 and Figure 4 shown, two buffer blocks 9 are arranged on the outer surface of the connecting plate 62 close to the first telescopic cover 61. Through the arrangement of the buffer blocks 9, when the tension spring 65 contracts and drives the connecting plate 62 to move and reset, the connecting plate 62 can be buffered, thereby ensuring the stability of the connection of the relevant structures.

[0039] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the transmission mechanism 8 includes an expansion body 81 arranged inside the first telescopic cover 61. The expansion body 81 is in contact with the connecting plate 62. The plurality of expansion bodies 81 are all fixedly connected to the box body 1. A pipeline 82 is arranged on the outer surface of the box body 1. The pipeline 82 is in contact with the cavity 3. A housing 83 is arranged on the outer surface of the pipeline 82. The housing 83 is fixedly connected to the box body 1. A pressure plate 84 is slidably connected to the inner wall of the housing 83. A sliding plate 85 is arranged on the outer surface of the pressure plate 84. The sliding plate 85 is slidably connected to the box body 1. A first connecting rod 86 is rotatably connected to the outer surface of the sliding plate 85. The first connecting rod 86 is rotatably connected to the box cover 2.

[0040] Specifically, as Figure 2 , Figure 3 and Figure 4 shown, the expansion body 81 is an airbag, which is usually made of lightweight and soft materials (such as rubber or polyvinyl chloride), and is lighter than other expansion bodies 81, which is beneficial to reducing the weight of the overall device.

[0041] Specifically, as Figure 1 and Figure 6 shown, the adjusting mechanism 7 includes a bidirectional lead screw 71 rotatably connected to the inner surface of the box cover 2. One end of the bidirectional lead screw 71 is provided with a rotating block 72. Two sliders 73 are threadedly connected to the outer surface of the bidirectional lead screw 71. Both sliders 73 are slidably connected to the box cover 2. A second connecting rod 74 is hinged to the outer surface of the slider 73. A lifting plate 75 is hinged to the outer surfaces of the two second connecting rods 74. The lifting plate 75 is fixedly connected to the first buffer pad 4. A plurality of limit expansion rods 76 are arranged on the upper surface of the lifting plate 75. All the plurality of limit expansion rods 76 are fixedly connected to the box cover 2.

[0042] Working principle: When in use, rotate the box cover 2 to open it. Drive the first connecting rod 86 to move by the rotation of the box cover 2. Then drive the sliding plate 85 to move by the movement of the first connecting rod 86, and further drive the pressing plate 84 to move, so that the air flow diffuses in the housing 83 and the pipeline 82, and then the expansion body 81 can be contracted, releasing the supporting state of the connecting plate 62. At this time, under the elastic force of the tension spring 65, the connecting plate 62, the third buffer pad 63 and the limiting rod 64 move and reset. At the same time, under the elastic force of the tension spring 65, the first telescopic cover 61 contracts and resets, leaving an operating space for placing the LED display screen;

[0043] Then place the LED display screens on the upper surface of the second buffer pads 5 respectively. At this time, the LED display screens can be laterally supported by the third buffer pads 63. Then rotate the box cover 2 to close it. Drive the first connecting rod 86 to move in the reverse direction by the rotation of the box cover 2. Then drive the sliding plate 85 to move in the reverse direction by the reverse movement of the first connecting rod 86, and further drive the pressing plate 84 to move in the reverse direction to pressurize the air flow inside the housing 83. The air flow enters the inside of the expansion body 81 through the pipeline 82 and the cavity 3, causing the expansion body 81 to expand. Then push the connecting plate 62 to move by the expanded expansion body 81, and further drive the third buffer pad 63 to move to laterally support and fix the LED display screens. During this process, the connecting plate 62 is limited by the limiting rod 64 to make the movement of the connecting plate 62 stable. At the same time, when the box cover 2 rotates and closes, it can drive the bidirectional lead screw 71, the rotating block 72, the sliders 73, the second connecting rods 74, the lifting plate 75, the limit expansion rods 76 and the first buffer pad 4 to rotate. When the first buffer pad 4 rotates and contacts the upper part of the LED display screen, the position fixing of the LED display screen can be completed. When the LED display screen is being transported, the LED display screen is buffered and protected by the first buffer pad 4, the second buffer pads 5 and the third buffer pads 63;

[0044] When protecting LED display screens of different heights, according to the actual situation, the rotating block 72 can be rotated. The rotation of the rotating block 72 drives the rotation of the bidirectional lead screw 71, and then the rotation of the bidirectional lead screw 71 drives the movement of the slider 73, thereby driving the movement of the second connecting rod 74. Then, the movement of the second connecting rod 74 drives the lifting plate 75 to move up or down, thereby driving the first buffer pad 4 to move to a suitable height to meet the requirements of supporting and fixing and buffering and protecting LED display screens of different heights. During this process, through the setting of the limit telescopic rod 76, the lifting plate 75 can be limited, so that the lifting plate 75 moves stably.

[0045] Embodiment 2

[0046] Please refer to Figure 7 , the present utility model provides a technical solution:

[0047] Different from Embodiment 1, a second telescopic cover 10 is arranged between the two sliders 73, and a third telescopic cover 11 is arranged on the outer surface of the slider 73 away from the second telescopic cover 10. Both of the two third telescopic covers 11 are fixedly connected to the box cover 2. The second telescopic cover 10 and the third telescopic cover 11 are both located outside the bidirectional lead screw 71.

[0048] Through the settings of the second telescopic cover 10 and the second telescopic cover 10, dust protection can be provided for the bidirectional lead screw 71, effectively avoiding the situation that dust particles adhere to the surface of the bidirectional lead screw 71 and increase wear, and thus the service life of the bidirectional lead screw 71 can be extended.
